Overview of LED Trac Clearing Light
Model LEDTCL64
The Federal Signal LED Trafc Clearing Light, Model
LEDTCL64 is a self-contained, high intensity LED light designed
for mounting to the exterior of a vehicle. The lights are supplied
with eight selectable ash patterns. The light heads work as a pair
and are synced together by connecting their sync wires. The light
head can operate on a 12 Vdc or 24 Vdc power source.
The light heads in this kit are identical; the ash pattern in each
light head is determined by the orientation of the light head. To
be an effective warning device, the internal circuitry of the lights
enables them to sense their orientation and automatically adjust the
ash pattern as an effective warning device.
An optional trim ring (QL64MC) can be purchased separately.

Unpacking Light
After unpacking the lights, inspect them for damage that may have
occurred in transit. If the lights are damaged, do not attempt to
install or operate them. File a claim immediately with the carrier,

Installing the Lights
NOTE: The light heads are to be installed in a horizontal
orientation, rotated 180 degrees from each other. (See Figure 1
on page 9).
To install the lights:
1. Determine the approximate locations of the light heads and
plan all wire routing.
2. Position a light head on the mounting surface. Ensure that
the light head is level-side to-side. Using the dimensions in
Figure 2 on page 10, scribe the locations of the four mounting
holes and a wire routing hole.
3. Complete Step 1 for the other light head.
4. For each light head, drill four 1/4 in (0.25 in) mounting holes
and a 1.00 in wire routing hole at the scribed locations.
5. Install the eight supplied rubber rivet nuts into the 1/4 in
mounting holes.
6. Complete the electrical connections in “Wiring the Lights.”
7. See Figure 1 on page 9. With the arrow on the inner lens
pointed toward the outer edge of the vehicle, align the light
heads with the rivet nuts.
8. Secure the light heads with the #6-32 S.S. screws.
Wiring the Lights
Refer to Table 3 and the instructions below.
Each light head has three 12 in long lead wires exiting the rear
of the housing. Ensure that all wires are properly terminated
and insulated.

Installation and Maintenance Instructions
LED Trac Clearing Light Model LEDTCL64
To wire the lights:
Use 18-gauge (minimum) wire to connect the RED (+) lead to
the positive power source terminal and the BLACK (–) lead to
the negative power source terminal.
2. Select a ash pattern as described in the next section.
3. When both light heads are set to the same ash pattern,
connect the GREEN wire from one light head to the other.
4. Apply power and test the lights for proper operation.
Selecting a Flash Pattern
Each light head has eight selectable ash patterns. When you
scroll through the patterns, the pattern number is represented by
the number of LEDs illuminated for one second before the pattern
starts. It is recommended that ash pattern is selected before the
installation. Because the lights are intended to be effective at large
distances, it is best to project the lights on a surface at least 15 feet
away. For the ash pattern descriptions, see Table 4.

3. Advance to the next pattern as needed.
4. Let the pattern run for at least 15 seconds to store it in
memory.
Safety Message to Operators
People’s lives depend on your safe use of our products. Listed
below are some important safety instructions and precautions you
should follow:
• Although your warning system is operating properly, it may
not be completely effective. People may not see or heed your
warning signal. You must recognize this fact and continue
driving cautiously.
• Also, situations may occur which obstruct your warning signal
when natural or man-made objects are between your vehicle
and others, such as raising your hood or trunk lid. If these
situations occur, be especially careful.
• This product contains high intensity LED devices. To prevent
eye damage, DO NOT stare into the light beam at close range.
• At the start of your shift, you should ensure that the light is
securely attached and operating properly.
Failure to follow these safety precautions may result in property
damage, serious injury, or death.

Cleaning the Lights
CRAZING/CRACKING Crazing (ne cracks) of lenses causes
reduced effectiveness of the light. Do not use cleaning agents
(which causes crazing) such as strong detergents, solvents,
or petroleum products. If crazing of the lens es does occur, the
reliability of light for emergency signaling purposes may be reduced
until the lenses are replaced.
NOTICE
CLEANING the POLYCARBONATE LENSES:To extend the life of this
device, periodic cleaning is necessary. Clean the lens with a mild,
non-abrasive, neutral-pH cleaning agent and a soft, clean cloth.
Rinse the device thoroughly to ensure that no cleaning agent residue
remains. To avoid water spots, dry the device with a soft clean cloth.
Failure to follow this precaution can cause crazing or cracking of the
lens/dome and voids the warranty claims for the light.
